Alternative Part Number

  • S29GL032N90TFI040 --: Spansion/Cypress 3V parallel NOR flash in the same 4 Mbit class with 90 ns access, a direct functional replacement for the Fujitsu MBM29LV400BC-90.
  • AM29LV400BT-90SI --: AMD/Spansion 4 Mbit 3V NOR flash with 90 ns speed grade, pin and function compatible with the Fujitsu device.
  • MX29LV400CTXBI-90G --: Macronix 4 Mbit 3V parallel NOR flash, 90 ns, commonly used as a drop-in alternative to Fujitsu MBM29LV400 series parts.
  • S29GL032N90TFI010 --: Spansion/Cypress 3V parallel NOR flash in the same 4Mbit-class family lineage as Fujitsu's MBM29LV series; 90ns access, widely available and pin-compatible in TSOP-48.
  • AM29LV400B-90SC --: AMD 4Mbit 3V parallel NOR flash with 90ns speed grade, functionally equivalent to the MBM29LV400BC-90 and a common drop-in replacement.
  • MX29LV400CT-90 --: Macronix 4Mbit 3V parallel NOR flash, 90ns, same command set and TSOP-48 footprint, offering a cost-effective second source.
